Title: Wire drawing furnace for optical fiber
Inventor: IDE TAKASHI
IPC: C03B37/029
Filed: 1986-05-06
Abstract: PURPOSE:To enhance gas sealing effect of a wire drawing furnace and reduce fluctuation of diameter of an optical fiber, by providing a small chamber at the tip end of the wire drawing furnace and adjusting the gas pressure in the small chamber higher than that in the wire drawing furnace. CONSTITUTION:In a wire drawing furnace 3 for melting an optical fiber preform 2 while heating and drawing the preform 2 into wires, the preform 2 is introduced from an inserting port therefore formed in a gas introduction ring port 1 provided on the upper end of the furnace 3. A sealing gas is introduced into an annular small chamber 10 provided in contact with the above-mentioned ring 1 to give a higher pressure than atmospheric pressure. Thereby the flow of rising air currents at a high temperature from the interior of the above- mentioned furnace 3 is prevented. As a result, the temperature distribution at the melt tip part of the preform 2 becomes uniform and the fluctuation in diameter of the fiber is reduced to afford the aimed excellent optical fiber.
